Claims.

This invention relates to radiators of the steam, vapor, and water heating type as well as those of the refrigerant cooling type which are at present held together with rods or bolts 5 that are exposed to view. The objects of my improvements are first, to conceal the rods or bolts from View; second, to accomplish this without contacting the rods or bolts with the steam, vapor, water, or refrigerant, thereby preventing the oxidization and corrosive action of the steam,

vapor, water, or refrigerant upon the rods or bolts; third, to present a smooth accessible surface for cleaning and painting, by concealing the rods; fourth, lessening the probability of accumu- 5 lating lint and dust between the radiator sections. This invention discloses a method for concealing the rods or bolts in any radiator, that requires rods or bolts to hold the sections together, to accomplish the indicated objects. This invention may be cheaply and simply made and requires only a small addition to the radiator sections.

Fig. 1 is an end elevation of a radiator end section, with one embodiment of my invention.

Fig. 2 is a fragmental side view of a portion of a radiator with the same embodiment of my invention.

Fig. 3 is an end elevation of a radiator end section showing the intermediate section with the same embodiment of my invention.

Fig. 4 is a fragmental end elevation of a radiator showing an intermediate section in a second embodiment of my invention.

Numeral 5 designates a conventional radiator having the end sections 6 and the intermediate sections 7. This invention does not concern itself with the fluid circulation system of the radiator, and finds application only witha radiator in which the sections are held together with rods or bolts.

Numerals 8 designate the legs of the end sections, numeral 9 designates the body portion of the'end section and numeral 10 the fluid inlet pipe to the end section. All the sections have columns 11; three column sections are illustrated in the drawing, but my invention is adaptable to radiator sections having a single column, or a plurality of columns. The columns are hollow. Numerals 12 designate the tubes at the bottom of the columns and numerals 13 designate the tubes at the top of the columns. The

tubes are placed in fluid communication by means of the vertical tubes 14 of the columns 11. The outer ends of one of the tubes 13 in the end sec tions are closed by the end closures 15. Numerals 16 designate shoulders or bosses formed integral with the inner face of the end sections around the tubes 12 and 13. Numerals 17 designate shoulders or bosses on the outer faces of the intermediate sections surrounding the tubes 12 and 13. The shoulders or bosses 16 of the end sections are placed in contact with the shoulders or bosses 17 of the adjacent intermediate sections '7. The shoulders or bosses 17 of the intermediate sections are likewise placed in contact 5 with each other. The sections are held together at the bottom by means of the rods or bolts 18 and 19, and at the top by means of the bolts or rods 20 and 21. In the conventional radiator construction the bolts 18, 19, 20, and 21 pass 7 through holes such as 22 in a web formed. above the tubes 12 on the outer side of the end sections 6 and between the columns of the intermediate sections. In the conventional structure the end sections are threaded at their free ends, and nuts such as 23 are placed in threaded engagement at the free ends of the rods or bolts 18, 19, 20, and 21. These bolts or rods are of such length that when the nuts 23 are secured tightly, the sections will be held together in their conso ventional position.

In this conventional structure it is seen that the bolts or rods 18, 19, 20, and 21 are exposed above the lower tubes 12 and below the upper tubes 13 intermediate the end sections. The dust, lint, and dirt collects on and around the rods or bolts 18, 19, 20, and 21 and particularly between the rods and the tops of the tubes 12 and the bottoms of the tubes 13. The space between the sections is necessarily small and it is extremely diflicult to clean between the sections beneath and around the rods or bolts indicated. Numerous attempts have been made to conceal these bolts or rods because of the difiiculty indicated. These rods can not be omitted in this type of radiator because they represent the simplest method for holding the columns in position. An attempt has been made to place the rods or bolts within the tubes 12 and 13 and secure them at their ends in spiders positioned in the ends of the tubes 12 and 13 in the end sections. This subjects the rods to the action of the fluid passing through the tubes 12 and 13. Under such fluid action they deteriorate rapid- 105 1y through oxidization and corrosion. This action is so rapid and deleterious that it has become necessary to abandon this method. No attempt has been made to indicate in the drawing or to describeherein the conventional method of forming a leak tight jointure between the sections by means of nipples or otherwise.

In my improvement the outer sides of the end sections are conventional as indicated in the drawing. The shoulder or bosses 16 and 17 of the conventional structure are considerably enlarged and the inner surface is arcuated as indicated at 2. by shoulders or bosses. These shoulders or bosses have the holes 25 formed in them through which the rods 18, 19, 20, and 21 are passed. In this construction the rods or bolts are secured to the end sections in the manner previously stated. The sections are likewise positioned as previously stated.

In the second form of my invention the enlarged bosses are hollow, that is to say; they are of the same size and shape as thesolid bosses previously described but are formed by the shell 26. In this form of construction the ends of the rods or bolts 18, 19, 20, and 21 are secured to the end sections in the same manner as previously described.

What I claim is:

l. A radiator section comprising fluid tubes and columns, the latter in fluid communication with the former, enlarged lateral bosses formed onsaid' tubes and having holes formed therein for the reception of rods.

2. A radiator section comprising fluid tubes and columns, the latter in fluid communication with the former, enlarged nipple bosses formed on said tubes, said bosses being hollow for the reception of rods.

3. A radiator comprising end and intermediate sections, each section having tubes formed therein.. lateral nipple bosses formed on said sections exteriorly, the inner portions of the bosses being enlarged and having holes passing therethrough, bolts passing through the holes in said inner enlarged bosses and held in frictional engagement with the end sections.

4. A radiator comprising end and intermediate sections, each section having tubes formed therein, lateral nipple bosses formed on said sections exteriorly, the inner portions of the bosses being enlarged and hollow, bolts passing through the-hollow portions of said enlarged bosses and held in frictional engagement with the end sections.

5. A radiator section comprising fluid tubes and columns, the latter in fluid communication with the former, enlarged nipple bosses formed on said tubes, said bosses being hollowed for the reception and concealment of rods.
